After regenerating my TOTP key for authenticator login, the Azure MFA configuration page https://mysignins.microsoft.com/security-info shows that I have two MFA login methods both simply described as "authenticator app". I would like to delete the old one, but because the lines are identical, I cannot tell which is which.

What is the solution to either delete the old one or replace both by a 3rd new one?

Note that I am using a hardware backed TOTP application, so using the default app that just stores secrets in phone memory is considered too insecure.

    The phone Microsoft Authenticator and email are all understandable. I am unsure what the "authenticator app" is
